The ratification of the Paris Agreement by the EU, representing 28 countries, on Oct. 4 marked the surpassing of the 55 percent global emissions threshold for the agreement to enter into force. Having been ratified by 75 countries that account for 58.9 percent of global emissions, the agreement will enter into force on Nov. 4 (30 days after EU submission), just a few days before the 22nd session of the Conference of Parties ( COP22 ) starts on Nov. 7 in Marrakech, Morocco.
